Solution

The correct option is B $50$ ohm
The minimum resistance possible by $5$ equal resistance(each of value $R$ ) is $\frac{R}{5}$ . This will happen when they will be in parallel.
So, $\frac{R}{5} = 2$
or, $R = 10$ ohm
The maximum resistance can be found when they will be in series i.e. $5 R = 50$ ohm.
